Breakdown of the Cross-Kerr Scheme for Photon Counting
Breakdown of the Cross-Kerr Scheme for Photon Counting
We show, in the context of single-photon detection, that an atomic three-level model for a transmon in a transmission line does not support the predictions of the nonlinear polarizability model known as the cross-Kerr effect. We show that the induced displacement of a probe in the presence or absence of …
